Ni Hao Guys,
Can you tell me how much RMB a CJ750 is? as NZ$3,500 seems very low.
Thankyou

I had one of these and it was a sidevalve 750. The sidecar was on the right. I had to vin it as a solo. The front brake on mine was barely adequate and the only reason they vinned it at all was it was " registerd " in China as a 59 and therefore over 20 years old.
The novelty of riding a bike that stuggled to do 80kmph soon wore off and I sold it.
I have seen them on the road so it must be possible, do the research first.

A brief history:
The original design is 1937 BMW and they were used in the early stages of WW2 prior to the introduction of the R75 which was OHV and had a driven wheel on the sidecar.
Its murky but the Germans either sold them to the Russians pre WW2 or the Russian reverse engineerd them and made them themselves.
After the war the Russians copied the R75 and later gave/sold the R71 knockoff to the Chinese who have been making them for years, mainly for the army.
The current ones look to be the Ural OHV style motor.

While its probably not a scam I'd advise steering clear of buying from China unless you get the goods first ( yeah right).
Their idea of well built and quality is far removed from ours.

Just for comparison, theres a secondhand Ural outfit on Tardme for $9500, so I think this falls into the category, "if it sounds too good to be true, its probably not true"

What's the rules about the sidecar being on the right hand side?
Does that mean it's a left hand drive bike?

another greyish area....the picture in the VIN book the man at VIN showed me did not stipulate left or right but showed left.
He suggested I take the sidecar off....which I did....
Believe me a mid 70's BMW 750/1000 with a sidcar is a far better option...unless you like to dwess up as WW2 Germans...: lol:

Yeah I saw one in Shanghai when I was there. They are actually quite sexy without the sidecar - but as stated by this guy, not legal on the road "as a bike" due to CC limits (150cc?) - contrary to a lot of the stuff out of china they seemed to be good quality, but old designs. So I imagine it will be like an old Triumph/BMW, never break but never run.
Would still be interested in the RMB price though - as I have just found out through marriage I have acquired a holiday home for our family in Shanghai.......WITH A GARAGE!!!!!
I am so stoked.

just share with you a new finished bike.
The owner has good taste, chose the best color , pin strip and decided which part should be shinning to match the bike.

Translation: cj750 sidecar is the most specialy vehical in China -- We put two wheels on it. Some of them are round.

But more and more people hope to get one -- High price ad man adviser from London tell us put that in. He make good joke, eh?

It's the replica of WWII BMW r71 and R75 -- we copied it from an old clipping we found from the Lenin Times newspaper. Early models have fold through middle of tank - very special

Keep very original WWII BMW elements -- The badge has a "B" in it. And it have wheels! Two!

Changjiang is the third generation of it -- we hit it more times with a hammer than those silly people at Ural


Bikes can be custom rebuilt by your taste -- We can use a much bigger hammer if you want to change shape

Can be shipped to many countries -- Just try coming to China and liding it home. Raugh will be on us.

Can be registered as antique bikes -- any bike you can still hit with hammer can be registered as old

changjiangsidecar shop offer high quality bikes to our high level customers -- best you have plennnnty to smoke of wacky backy if buy one of these babies

W ith two years warrenty for any parts and any problem -- good joke eh? Chinaman make good joke all time now

You can vivist or contact changjiangsidecar shop as below -- come on vivist us tydao!

A bit more seriously: when they say "can be registered as antique/vintage/whatever", what they mean is that they will provide you via a dodgy agent with a document showing your newly-made Chang Jiang was actually built in 1958.

So beware. Several folk in NZ have been trapped with this dodge, which the NZ rego authorities take as an affront to their intelligence, and rightly so.

That having been said, the product ain't all bad. One of my mates put a motor out of a crashed BMW R90 into his, and got a machine he really liked. The sidevalve CJ donk looks kinda cool in a retro way, but has roughly the same power and reliability as a mayfly.

You are right about the dodgy documents, some of the ohv motors were made up to 2002. I got the original rego documents with mine so I had no problems.

I haven't had this one for long and I am still sorting out the last of the restoration based problems with it. The motor is fine but the bike was put together by an idigit. I got this as a low cost alternative to a Harley WLA which were available but this was only 20% the cost.

It seems that the greatest reliability issue is overheating. These ex PLA military bikes always had throttle stops, which every civilian removes. The std PLA bikes all ran on the needle jet and never got open enough to use the main jet which was actually too small. So they ran very hot if used at high speed and melted the pistons. Easy fix is to re-jet the carbs.

I know personally of 3 other in NZ, and we all share parts and experience. The folk that I know with them all love these funny little bikes to bits. Mine seems to pop along at 80kph ok which is fine for a 30's technology side valve bike with a side car. I don't think it would do this speed with the factory jets for long.

There we are - nothing like a report from personal experience.

I had one for a while, and have to agree with Flip , as a budget contempory of the WLA it does the job fine. As a touring sidecar outfit it leaves a lot to be desired.
I took my BMW r75/5 Watsonian GP combination to the Elefant Rally and up as far as the Artic Circle in Norway, it was( is) a very good sidecar machine and could cruise at motorway speeds all day long.

As cool looking as the CJ are they are not that great to ride in modern traffic....in my opinion.
My one got sold to a guy in the south to use for war re enactments.....perfect.

There is very few 30's or 40's technology vehicles that are any good in modern traffic, they are all slow and under powered. Some of the bigger American cars are not too bad as are the top of the line OHV Harlie's, but these are all from the very late 40's. My CJ has just started to run very well now that it has 1000 miles on it. Its due a meeting with the porting tool in the very near future, I will get a few more HP from it yet.
